MATLAB: Error code on cumsum cumsum I am attempting to run: A = 1 – cumsum(C)/sum(C); where C is a long column vector. I receive error "??? Error using ==> cumsum CUMSUM is not supported for integer input." What does it mean? Best Answer Try this. It works for me:C = int32(randi(9, 1, 10)) % Array of integers.A = 1 - cumsum(C) / sum(C) Related SolutionsMATLAB: Error using ‘graph’ function in matlab R2019b Could you try starting a new MATLAB and just enter the following code:>> A = ones(3);>> G = graph(A);If this gives the error message you mentioned, could you again run the following lines on command line?>> T = table(nonzeros(tril(A)), 'VariableNames', {'Weight'})>> istable(T)>> class(T)If this returns true and 'table', we'll have a deeper mystery to solve. If not, please let us know what is being displayed for you. MATLAB: Built-in min() function has stopped working. My apologies - stupid mistake has been located. A variable representing minutes shares the function name "min".
